Re: bash 4 parse error on here-document in $()

[Martin Sebor]

Thank you for setting me straight! I had checked the POSIX spec
before sending the report but missed the part about the delimiter
having to be immediately followed by newline.

Description:
        Bash 4.0 errors on a here-document enclosed in $(). For example:
        x=$(cat<<EOF
        foo
        bar
        EOF)
        Ctrl+D
        -bash: unexpected EOF while looking for matching `)'
        -bash: syntax error: unexpected end of file

The shell is allowed to do this.  A here-document is supposed to be
terminated by a line containing the delimiter followed by a newline,
not EOF.

However, the behavior is useful enough that I changed the parser to
support it in bash-4.1.
